Abstract
Uterine cervical conization is related to adverse pregnancy outcomes in subsequent pregnancies To deal with this problem we started conservative coinshaped conization for reproductiveaged patients with cervical intraepithelial neoplasia CIN Here we report both the obstetrical and oncological impacts of this operation in comparison with the standard coneshaped resectionA total of 401 women 44 years old or younger were treated in our hospital by CO2 laser conization between 2003 and 2012 and subsequently 50 patients became pregnant The patients were divided into two groups a standard coneshaped conization group until 2008 and a shallow coinshaped conization group beginning in 2008 The pregnancy courses and oncological prognoses of these two groups were studiedCone height reduction of about 3 mm was done However there were no significant differences between the two groups with regard to the occurrence of oncological complications In the standard conization group 18 of the 25 patients delivered at term In the coinshaped conization group 20 of the 25 patients delivered at term There were no significant differences between the two groups with regard to the occurrence of various obstetrical complications However the reduction rate of cervical length over the pregnancy was smaller in the coinshaped group and the number of patients with a short cervix length of 2 cm or less was smaller in the coinshaped group
